Description

The snmptrap utility is an SNMP application that uses the SNMP TRAP
operation to send information to a network manager. You can specify one
or more object identifiers (OIDs) on the command line. A type and
a value must accompany each object identifier. Each variable name must be entered
in the format specified in snmp_variables(4).

When invoked as snmpinform, or when you specify the -Ci option to
snmptrap, it sends an INFORM-PDU, expecting a response from the trap receiver,
and retransmitting if required. Otherwise, it sends a TRAP-PDU or TRAP2-PDU.

If any of the required version 1 parameters—enterprise-oid, agent, and uptime—are specified
as empty, they default to 1.3.6.1.4.1.3.1.1 (enterprises.cmu.1.1), hostname, and host-uptime respectively.
